The Obsidia Advantage

FOR GRID ENERGY STORAGE

Longer operational life. Deeper discharge capability. Built for practical integration.

Obsidia is designed to address several performance limitations affecting long-duration energy storage systems, including anode swelling, degradation from repeated cycling, and reduced usable capacity due to conservative discharge limits.

As a graphite-blend additive, Obsidia can be evaluated within existing lithium-ion manufacturing processes, helping reduce adoption friction while supporting practical deployment pathways for grid-scale battery systems.

Utility-Scale Battery
Energy Storage Systems

Large-scale storage projects require battery systems capable of maintaining reliable performance across years of repeated charge and discharge cycles. Long-term operational stability directly affects maintenance costs, replacement schedules, and project ROI.

The Advantage:

  • Extended cycling durability
  • Lower swelling under repeated cycling
  • Longer operational service life
Renewable Energy
Integration

Battery systems supporting solar, wind, and hybrid renewable infrastructure must handle frequent cycling and variable load demands while maintaining stable long-term performance. 

The Advantage:

  • Deeper discharge tolerance
  • More usable stored energy
  • Reliable long-term cycling
Backup Power &
Critical Performance

Grid backup systems supporting utilities, municipalities, data infrastructure, and emergency-response environments require battery systems that remain dependable during extended standby periods and perform reliably when called upon. 

The Advantage:

  • Long-storage stability
  • Reliable standby performance
  • Durable operation under high-demand cycling

Working With Us

Designed for operational integration.

Obsidia is available as a graphite-blend additive for existing lithium-ion anode formulations. At blend ratios around 10% or lower, cell manufacturers can evaluate Obsidia within conventional production workflows without major changes to cell-line equipment.

C-BATT works directly with battery manufacturers, integrators, and energy storage developers, evaluating long-duration storage systems and domestic sourcing strategies for battery materials.

Domestic Supply Chain

As domestic energy infrastructure continues to expand, battery supply-chain resilience is becoming increasingly important for utilities, developers, and energy storage programs. Federal incentives and domestic sourcing requirements are also driving a greater demand for U.S.-based battery material production.

C-BATT has verified Obsidia’s supply chain down to basic chemical inputs. All material inputs come from U.S. suppliers using U.S.-manufactured materials. Developed in Florida and produced in West Virginia, Obsidia provides defense battery manufacturers with a fully domestic anode material built for performance, traceability, and scalability.

Backed by Core Natural Resources, C-BATT combines verified U.S. sourcing with industrial infrastructure positioned for American battery-material production.

Frequently Asked Questions

How does Obsidia support longer operational life in grid storage systems?

Obsidia’s low swelling characteristics help reduce anode degradation during repeated cycling. Lower expansion during charge and discharge cycles may support longer-lasting battery performance and reduced long-term degradation compared to conventional graphite-only systems.

Can Obsidia support deeper discharge capability?

Obsidia is designed to improve tolerance under deep-discharge and low-voltage conditions, helping battery systems maintain more usable capacity while supporting long-term durability.

Does integrating Obsidia require major manufacturing changes?

No. Obsidia is available as a graphite-blend additive for existing lithium-ion anode formulations. At blend ratios around 10% or lower, manufacturers can evaluate the material within conventional production workflows without major cell-line modifications.

Why does domestic sourcing matter for grid energy storage?

Utilities, developers, and energy infrastructure programs are increasingly evaluating supply-chain resilience, domestic content requirements, and long-term sourcing stability. C-BATT’s fully domestic supply chain helps support those priorities while reducing dependence on foreign-dominated graphite supply chains.

Is Obsidia commercially available for evaluation?

Yes. C-BATT supports material evaluations through technical documentation, sample materials, and application-specific discussions with qualified manufacturers and development teams.
